How to use

In Vitro:

Epothilone A, discovered from the myxobacterium Sorangium cellulosum, is a Taxol-like microtubule-stabilizing agent that induces tubulin polymerization, leading to cell cycle arrest at the G2-M transition, cytotoxicity, and apoptosis.Epothilone A potently inhibits cell proliferation in HCT116 cells, with IC50 of 4.4 nM. Epothilone A also displays cytotoxicity in KB3-1, KBV-1, Hela, and Hs578T cells, with IC50 values ranging from 13 nM to 160 nM. Epothilone A is more water soluble than Taxol and competes with Taxol in binding with microtubules, with IC50 of 2.3 μM. However, both Epothilone A and Taxol don't share a common pharmacophore and exploits the tubulin-binding pocket uniquely and independently. Recently, it is found that microbiological transformation of Epothilone A by Aspergillus niger AS 3.739 yields several metabolites that is also toxic to MCF-7 cells, but with much higher IC50 values.
